>> chris: let me ask you about the additional complications, because it now turns out the way the f.b.i. found out about that is because paula broadwell, the mistress, was sending threatening e-mails to another woman, whom she regarded as a threat to her relationship with petraeus. what do you know about that relationship between the other woman and petraeus? >> well, there is an f.b.i. investigation. that is continuing. i read "the post" and "the times" this morning and it's pretty well laid out, i think. i just hate to discuss it except to say there are a number of things that one has to consider, the first of which was there any kind of national security breach? to date, there was not. and the f.b.i. briefed me now. i actually wish we had been briefed a little bit earlier. so that the full intelligence committee, one of the things that i tried to do, chris, is bring both sides together.
